AWS start instance from cmd line specifying args to launch script

Question

I need to be able to startup AWS EC2 instances quickly from one of my AMI images and at launch run a script to bootstrap the instance. I know I can do this with user data but I need to be able to pass the script an argument that will be different each time the instance is started.

If I use Start-EC2Instance from AWS Tools I cant see a way to either pass the user data or pass agrs to the launch script.

Any help would be much appreciated.

Thanks
